IMPROVEMENT IN MUSlC-LEAF TURNERS Specification forming part of LettersPatent No. 159,101 dated January 26, 1875; application filed April 18,1874.

To all whom it may concern:

Be it known that I, WILLIAM H. KING, of Petersburg, in the county ofPike and State of Indiana, have invented a new and Improved Attachmentto Music-Leaf Turners, of

which the following is a specification:

In the accompanying drawing,.l igure 1 represents a front elevation ofmy improved attachment to music-leaf turner as applied to the piano orother instrument in connec tion with my music-leaf turner; and Figs. 2and 3, respectively, are a detail bottom view and vertical transversesection of the lever and ratchet'plate for opera-tin g theleaf-turner.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide for use in connection with mymusicleat turner, patented to me under date of January 6, 187 3, andnumbered 146,188, an attachment for turning the same by means of the legor'foot, so that the time-consuming use of the hands is entirelydispensed with, and the arms quickly and neatly turned at the requiredmoment.

My invention consists of anattachment consisting of a cord fastened by ahook and elastic strap to the left side of the 1nusi0- rack, to be thenwound around the knob of my musicleaf turner, passing then over suitable pulleys to a lever pivoted to the under side of the piano,musicstand, or other article, the front part of which is acted upon byahing'ed' plate with segmental ratchet, and operated by the leg or foot,turning the leaves,on raising the ratchet-plate, by means of the elasticstrap in one direction, and by means of the lever in opposite direction.

In the drawing, A represents the cord, and B the lever-and-ratchetmechanism, of my attachment to music-leaf turner. Cord A is applied atthe left-hand side of the music rack of piano or other musicalinstrument or music-stand, after the leat turner has been attachedto-the main part thereof, in the position required.

A hook or any other fastening device, a,

- may be used for attaching cord A to the rack,

an elastic strap or spring, I), of rubber or other material, forming theconnection of fastening a, and the end of cord A. Cord A is then Woundaround the knob of my leafturner, and passed over suitable pulleys, 01,applied at the side of the piano or similar inbase-plate, as desired. Itconsists of lever U,

which is pivoted centrally to the instrument, with cord A attached toits rear end by means of a slit and set-screw, f. The recessed front oflever O has a metallic catch, 9, for looking into the teeth of asegmental ratchet, D, of a plate, E, which is hinged to the instrumentunder right angles to lever O.

The ratchet-plate D E acts on the lever C, until raised by means of theleg or foot, dropping instantly back on the lever as soon as released.

the leaves attached to the arms of the turner to the right. The elasticstrap is thereby stretched, and turner and attachment ready for theplayer.

A simple touch of the ratchet-plate by the leg or foot ofthe playerreleases the lever, and producestheinstant turning of the leat by theaction of the elastic strap and cord, which is repeated as required,forming therebya very convenient and simple device for operating themusic-leaf turner and the leaves without the use of the hands.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The pivoted lever 0, having cord A attached to itsrear end, and catch 9 at its recessed front end, in combination withsegmental ratchet-plate D E, hinged sidewise and laterally to lever O,to operate as described.

WILLIAM H. KING.
